Faculty Scholarship
We describe the successful detection of human, porcine and canine picornaviruses (CanPV) in sewage sludge (at each stage of treatment) from Louisville, Kentucky, USA, using Pan-enterovirus amplicon-based long-read Illumina sequencing. Based on publicly available sequence data in GenBank, this is the first detection of CanPV in the USA and the first detection globally using wastewater-based epidemiology. Our findings also suggest there might be clusters of endemic porcine enterovirus (which have been shown capable of causing systemic infection in porcine) circulation in the USA that have not been sampled for around two decades. Our findings highlight the value of WBE coupled …
Ecological Protection Alone Is Not Enough To Conserve Ecosystem Carbon Storage: Evidence From Guangdong, China, Lihan Cui, Wenwen Tang, Sheng Zheng, Ramesh P. Singh
Ecological Protection Alone Is Not Enough To Conserve Ecosystem Carbon Storage: Evidence From Guangdong, China, Lihan Cui, Wenwen Tang, Sheng Zheng, Ramesh P. Singh
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
The increase in atmospheric CO2 caused by land use and land cover change (LUCC) is one of the drivers of the global climate. As one of the most typical high-urbanization areas, the ecological conflicts occurring in Guangdong Province warrant urgent attention. A growing body of evidence suggests LUCC could guide the future ecosystem carbon storage, but most LUCC simulations are simply based on model results without full consistency with the actual situation. Fully combined with the territorial spatial planning project and based on the land use pattern in 2010 and 2020, we have used the Markov and Patch-generating Land …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
The rise in wildfire frequency and severity across the globe has increased interest in secondary succession. However, despite the role of soil microbial communities in controlling biogeochemical cycling and their role in the regeneration of post-fire vegetation, the lack of measurements immediately post-fire and at high temporal resolution has limited understanding of microbial secondary succession. To fill this knowledge gap, we sampled soils at 17, 25, 34, 67, 95, 131, 187, 286, and 376 days after a southern California wildfire in fire-adapted chaparral shrublands. We assessed bacterial and fungal biomass with qPCR of 16S and 18S and richness and composition …

Equivalent Hazard Magnitude Scale, Yi Victor Wang, Antonia Sebastian
Equivalent Hazard Magnitude Scale, Yi Victor Wang, Antonia Sebastian
Institute for ECHO Articles and Research
Hazard magnitude scales are widely adopted to facilitate communication regarding hazard events and the corresponding decision making for emergency management. A hazard magnitude scale measures the strength of a hazard event considering the natural forcing phenomena and the severity of the event with respect to average entities at risk. However, existing hazard magnitude scales cannot be easily adapted for comparative analysis across different hazard types. Here, we propose an equivalent hazard magnitude scale to measure the hazard strength of an event across multiple types of hazards. We name the scale the Gardoni Scale after Professor Paolo Gardoni. We design the …

Relative Importance Of Radar Variables For Nowcasting Heavy Rainfall: A Machine Learning Approach, Yi Victor Wang, Seung Hee Kim, Geunsu Lyu, Choeng-Lyong Lee, Gyuwon Lee, Ki-Hong Min, Menas C. Kafatos
Relative Importance Of Radar Variables For Nowcasting Heavy Rainfall: A Machine Learning Approach, Yi Victor Wang, Seung Hee Kim, Geunsu Lyu, Choeng-Lyong Lee, Gyuwon Lee, Ki-Hong Min, Menas C. Kafatos
Institute for ECHO Articles and Research
Highly short-term forecasting, or nowcasting, of heavy rainfall due to rapidly evolving mesoscale convective systems (MCSs) is particularly challenging for traditional numerical weather prediction models. To overcome such a challenge, a growing number of studies have shown significant advantages of using machine learning (ML) modeling techniques with remote sensing data, especially weather radar data, for high-resolution rainfall nowcasting. To improve ML model performance, it is essential first and foremost to quantify the importance of radar variables and identify pertinent predictors of rainfall that can also be associated with domain knowledge. In this study, a set of MCS types consisting of …
A Causal-Comparative Study Of The Impact Of Meaningful Watershed Environmental Experiences On The Academic Achievement Of Middle School Students, Gina R. Mason
Doctoral Dissertations and Projects
Meaningful watershed educational experiences (MWEE) are student-centered, problem solving-oriented environmental educational experiences in which students investigate local environmental issues leading to civic engagement and informed action. The four components of an MWEE include issue definition, outdoor field experience, synthesis and conclusion, and action projects. While multiple benefits have been shown to be gained through participation in environmental education, this study’s aim was to observe the impact MWEEs have on academic achievement in middle school students. This quantitative, ex post facto, causal-comparative study examined the impact MWEEs had on students’ achievement scores, as measured by Pennsylvania System of School Assessment (PSSA) …

Mussel Squeeze: Dissolved Oxygen And Temperature Can “Squeeze” Zebra Mussels Out Of Invaded Reservoirs, Crysta A. Gantz, Rich Miller, Steve Wells, Mark Sytsma, Angela Lee Strecker
Environmental Sciences Faculty and Staff Publications
Zebra mussels (Dreissena polymorpha) are an aquatic invasive species that cause extensive economic and ecological impacts and are a management priority in areas outside of their native range. Survivorship and distribution of zebra mussels within a waterbody are thought to be influenced by temperature and dissolved oxygen conditions, but detailed information to confirm the importance of these environmental controls is necessary to inform management efforts. We measured planktonic zebra mussel veliger density and adult survivorship in San Justo Reservoir in central California to determine distribution and timing of spawning in relation to temperature and dissolved oxygen throughout winter, spring, and …

Possible Overestimation Of Nitrogen Dioxide Outgassing During The Beirut 2020 Explosion, Ashraf Farahat, Nayla El-Kork, Ramesh P. Singh, Feng Jing
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
On 4 August 2020, a strong explosion occurred near the Beirut seaport, Lebanon and killed more than 200 people and damaged numerous buildings in the vicinity. As Amonium Nitrate (AN) caused the explosion, many studies claimed the release of large amounts of NO2 in the atmosphere may have resulted in a health hazard in Beirut and the vicinity. In order to reasonably evaluate the significance of NO2 amounts released in the atmosphere, it is important to investigate the spatio-temporal distribution of NO2 during and after the blast and compare it to the average day-to-day background emissions from …

Crisisready's Novel Framework For Transdisciplinary Translation: Case-Studies In Wildfire And Hurricane Response, Andrew Schroeder, Caleb Dresser, Akash Yadav, Jennifer Chan, Shenyue Jia, Caroline Buckee, Satchit Balsari
Institute for ECHO Articles and Research
Extreme weather events including wildfires and hurricanes are becoming increasingly hazardous due to climate change, and often result in transient or permanent population displacements. Disaster-related disruptions in infrastructure, workforce, wages, and social networks can combine with population displacements to result in interruptions in health care access and prolonged impacts on morbidity and mortality. The data needed to make health systems and emergency management approaches more resilient to these hazards, and more responsive to the needs of affected populations, are sequestered in silos across private corporations and public agencies. In two case studies, we describe how our research team at CrisisReady …
Outdoor Recreation And Its Effect On Our Relationship With The Environment, Martin Brannaman
Outdoor Recreation And Its Effect On Our Relationship With The Environment, Martin Brannaman
Department of Environmental Studies: Undergraduate Student Theses
This study was conducted at the University of Nebraska Outdoor Adventure Center. This study employed a pre-post retrospective assessment looking at individuals' connection with nature after embarking on a direct outdoor experience. A direct outdoor experience is when an individual is outside and not surrounded by manmade structures (Kil, 2016). I believe that after a direct outdoor experience the sample group will have a significant change in their connection to nature. The objective is to measure change in a group's connection to nature, through the Connectedness to Nature Scale (CNS, Mayer & Frantz, 2004). The population was a group of …
Eastern Redcedar Reduces Regeneration And Diversity In The Forests Of The Niobrara River Valley, Abigail Ridder
Eastern Redcedar Reduces Regeneration And Diversity In The Forests Of The Niobrara River Valley, Abigail Ridder
Department of Environmental Studies: Undergraduate Student Theses
Boundary forests are found growing interdigitated with grasslands across the Great Plains. The Niobrara River valley boundary forest has a unique composition of species not seen anywhere else in North America. Encroachment of eastern redcedar (Juniperus virginiana L.) into grasslands and forests is significantly increasing eastern redcedar’s presence in the Niobrara River Valley as well as in the rest of the Great Plains region. This tree species is capable of significantly decreasing recruitment and diversity in grasslands, which can change the composition of the entire ecosystem. However, the effect of eastern redcedar on recruitment and diversity of naturally forested ecosystems …
Literature Review On Water Desalination Plant Production And Brine Disposal Methods, Grace Kollars
Literature Review On Water Desalination Plant Production And Brine Disposal Methods, Grace Kollars
Department of Environmental Studies: Undergraduate Student Theses
Water scarcity is an issue all around the world because people have a lack of clean and available drinking water. One way this issue can be eased and people can have more access to water is implementing water desalination plants around the world. Since most of the water on earth cannot be drunk, there are ways to turn the over abundance of salty waters we have on this planet into fresh, drinkable water to ease the water insecurity. There are many methods out there that can be used for water desalination, most of them involving membrane technologies. The most efficient …

Analyzing Recycling Options For Wind Turbine Blade Waste, Awinita Bunner
Department of Environmental Studies: Undergraduate Student Theses
The purpose of this study was to conduct a systematic literature review to identify recycling options for wind turbine blade waste. Wind energy is a rapidly growing energy source due to its renewability and accessibility. However, the turbines that produce this energy have blades that must be replaced throughout the turbine’s lifetime. The standard disposal method of decommissioned blades is the landfill. However, problems are arising within states as landfills are being overrun by the wind turbine blades once they reach their end-of-life. Conducting this study aims to provide a list of recycling options and provide an evaluation of each …

Spatial Validation Of Agent-Based Models, Kristoffer Wikstrom, Hal T. Nelson
Spatial Validation Of Agent-Based Models, Kristoffer Wikstrom, Hal T. Nelson
Public Administration Faculty Publications and Presentations
This paper adapts an existing techno–social agent-based model (ABM) in order to develop a new framework for spatially validating ABMs. The ABM simulates citizen opposition to locally unwanted land uses, using historical data from an energy infrastructure siting process in Southern California. Spatial theory, as well as the model’s design, suggest that adequate validation requires multiple tests rather than relying solely on a single test-statistic. A pattern-oriented modeling approach was employed that first mapped real and simulated citizen comments across the US Census tract. The suite of spatial tests included Global Moran’s I, complemented with bivariate correlations, as well as …

The reservoir for zoonotic o’nyong-nyong virus (ONNV) has remained unknown since this virus was first recognized in Uganda in 1959. Building on existing evidence for mosquito bloodfeeding on various frugivorous bat species in Uganda, and seroprevalence for arboviruses among bats in Uganda, we sought to assess if serum samples collected from bats in Uganda demonstrated evidence of exposure to ONNV or the closely related zoonotic chikungunya virus (CHIKV). In total, 652 serum samples collected from six bat species were tested by plaque reduction neutralization test (PRNT) for neutralizing antibodies against ONNV and CHIKV. Forty out of 303 (13.2%) Egyptian rousettes …
